Hello, tell me a lot about your technical skill sets and if you have a multi meter or not so that I can coach you most efficiently
Thanks, ***** ***** front portion of the thermostat gently from its wall mounting plate,
you will see the thermostat wires connected to various terminals marked R, Y, W, G and etc
Tell me which color wires go to which terminals and I will prescribe some tests that you can do.
See if you can push the tabs at the bottom in slightly and release the bottom if that works then lift thermostat up and out
(when prying you need to pry in the tiny gap between the wall mounted plastic plate and the operating front end of the thermostat... do not try to pry the wall plate off of the wall)...if you are in the right spot it should move fairly easily, then work your way around the perimeter evenly until you separate the front end from the wall plate mount,)
Good work, that is a special type of thermostat, I need the brand and model number of it, that is inked in on the back of the thermostat as you are holding it in your hand,
Thanks, ***** ***** a communicating type thermostat, (means the thermostat has a micro computer that monitors the furnace and AC unit performance against the room air temperature conditions and fine tunes the system accordingly).
It is nothing that can repair your self. The most you can do is to check for 24volts between R and C...that would tell us if you have a burned out 24v transformer or fuse in that circuit or not,
There is nothing we can jumper to test the system as with conventional thermostats.
that is the manual for what its worth. You will have to call the dealer on this one.
Let me know if you are happy with them or not, if not I can look for a better qualified dealer in your area.
Thanks, ***** ***** like the thermostat display has failed... testing other causes is quite complex, most techs would just replace the thermostat. With Lennox this is something that they must do, sorry about that... but that is the situation with lennox, they like to make proprietary equipment.
Stay in touch if you have any trouble at all contacting or working with the dealer who installed the system,
